City of Thornton Red-Light and Mobile Speed Automated Photo Safety Program
The City of Thornton and the Thornton Police Department are working to improve community safety by installing state-of-the-art digital red-light safety cameras and mobile speed cameras to decrease traffic violations and collisions and to help increase safety in our community.
Thornton has partnered with Verra Mobility to install red-light safety cameras at two intersections:
East 88th Avenue and Washington Street - Warning period start date TBD
East 120th Avenue and Colorado Boulevard - Warning period start date TBD
To reduce excessive speeding, Thornton will also place mobile speed cameras at various high-risk locations in the city (warning period start date: Nov. 25, 2025). All cameras will be operational by the end of 2025.
These cameras have been proven effective in reducing crashes and serious injuries. We want to stop this behavior before it becomes even more dangerous, or even fatal.
Verra Mobility’s programs across the U.S. gathered 4.6 million red-light citations in 2023, with a recidivism rate of 84%, meaning most violators did not repeat their illegal behavior. Speed programs issued 11.6 million speed citations with a 62% recidivism rate.
This is just one of the many tools Thornton is employing to keep the community safe.
Frequently Asked Questions
Red-light cameras have been proven to be effective in reducing red-light violations and right-angle collisions, and speed cameras consistently lessen reckless speeding and reduce pedestrian-related accidents. Municipalities using these systems consistently report safer roads with fewer collisions.
-
A Notice of Violation for a red-light violation is issued when a vehicle fails to stop at a clearly marked stop line or at any other stopping point described in the ordinance when facing a steady circular red signal, or if the vehicle does not come to a complete stop before making a right turn. Similarly, a Notice of Violation is issued when a vehicle fails to comply with the posted speed limit.
-
The fine for a red-light violation is $75. Failure to respond to a Notice of Violation, failure to appear for a requested hearing, or failure to pay a penalty imposed after a hearing may result in the issuance of a Summons and Complaint with personal service at an additional charge of $18. Once personal service has been provided, your appearance in court will be required.

Identifies the driver of the vehicle.
How do mobile speed cameras work?
Step 1: The system activates when a vehicle is detected traveling in excess of the posted speed limit.
Step 2: The system takes an image of the front of the vehicle to identify the driver.
Step 3: The system takes an image of the rear of the vehicle to identify the license plate.
Step 4: Additional data collected includes the time, date, posted speed, vehicle speed, location, lane and direction of travel.
Step 5: The police review the images and data captured by the system to determine whether to issue a violation notice.
